How to implement a model/class to work with EF?

Question

.NET

I send a post request from the client to the server in json format with the following content:

{
“adres” : “Street”,
“goods” : [
{
“name” : “apple”,
“count” : 1
},
{
“name” : “melon”,
“count” : 1
}]
}

How to build a model structure on the server?
As the accepted parameter of the controller method I use
[FromBody]<Order> Order
